All I can suggest is that you open the receiver and check the amplifier board voltages are all OK or if there are any obvious signs of component damage e.g. burnt out or heat stressed components.
The power board seems to be OK as you said the receiver turns on, although this doesn't mean that it is supplying the correct voltages to the amp board.
Without a schematic for the receiver it is difficult to know.
I assume that it is no longer covered by any manufacturer's warranty?
If it is, don't open it up as this will void the warranty. Contact Fussion in you location about a repair.

This is all I could find regarding the receiver which is not very useful as it doesn't even offer a user manual to know what features it has.
Does the receiver have an headphones socket?
If so do you hear audio when plugging a set of headphones into the socket?
have you checked that you have selected the correct input source for the audio to be heard?
